The EFI handover protocol was introduced on x86 to permit the boot
loader to pass a populated boot_params structure as an additional
function argument to the entry point. This allows the bootloader to
pass the base and size of a initrd image, which is more flexible
than relying on the EFI stub's file I/O routines, which can only
access the file system from which the kernel image itself was loaded
from firmware.
This approach requires a fair amount of internal knowledge regarding
the layout of the boot_params structure on the part of the boot loader,
as well as knowledge regarding the allowed placement of the initrd in
memory, and so it has been deprecated in favour of a new initrd loading
method that is based on existing UEFI protocols and best practices.
So update the x86 boot protocol documentation to clarify that the EFI
handover protocol has been deprecated, and while at it, add a note that
invoking the EFI handover protocol still requires the PE/COFF image to
be loaded properly (as opposed to simply being copied into memory).
Also, drop the code32_start header field from the list of values that
need to be provided, as this is no longer required.

0698fac4ac ("efi/arm: Clean EFI stub exit code from cache instead of avoiding it")
introduced a PC-relative reference to 'call_cache_fn' into
efi_enter_kernel(), which lives way at the end of head.S. In some cases,
the ARM version of the ADR instruction does not have sufficient range,
resulting in a build error:
arch/arm/boot/compressed/head.S:1453: Error: invalid constant (fffffffffffffbe4) after fixup
ARM defines an alternative with a wider range, called ADRL, but this does
not exist for Thumb-2. At the same time, the ADR instruction in Thumb-2
has a wider range, and so it does not suffer from the same issue.
So let's switch to ADRL for ARM builds, and keep the ADR for Thumb-2 builds.

Commit
d5cdf4cfea ("efi/x86: Don't relocate the kernel unless necessary")
tries to avoid relocating the kernel in the EFI stub as far as possible.
However, when systemd-boot is used to boot a unified kernel image [1],
the image is constructed by embedding the bzImage as a .linux section in
a PE executable that contains a small stub loader from systemd that will
call the EFI stub handover entry, together with additional sections and
potentially an initrd. When this image is constructed, by for example
dracut, the initrd is placed after the bzImage without ensuring that at
least init_size bytes are available for the bzImage. If the kernel is
not relocated by the EFI stub, this could result in the compressed
kernel's startup code in head_{32,64}.S overwriting the initrd.
To prevent this, unconditionally relocate the kernel if the EFI stub was
entered via the handover entry point.

Commit
3ee372ccce ("x86/boot/compressed/64: Remove .bss/.pgtable from bzImage")
removed the .bss section from the bzImage.
However, while a PE loader is required to zero-initialize the .bss
section before calling the PE entry point, the EFI handover protocol
does not currently document any requirement that .bss be initialized by
the bootloader prior to calling the handover entry.
When systemd-boot is used to boot a unified kernel image [1], the image
is constructed by embedding the bzImage as a .linux section in a PE
executable that contains a small stub loader from systemd together with
additional sections and potentially an initrd. As the .bss section
within the bzImage is no longer explicitly present as part of the file,
it is not initialized before calling the EFI handover entry.
Furthermore, as the size of the embedded .linux section is only the size
of the bzImage file itself, the .bss section's memory may not even have
been allocated.
In particular, this can result in efi_disable_pci_dma being true even
when it was not specified via the command line or configuration option,
which in turn causes crashes while booting on some systems.
To avoid issues, place all EFI stub global variables into the .data
section instead of .bss. As of this writing, only boolean flags for a
few command line arguments and the sys_table pointer were in .bss and
will now move into the .data section.

Auditing tcs_invalidate() made me worried. Specifically I saw that it
used spin_lock(), not spin_lock_irqsave(). That always worries me
unless I can trace for sure that I'm in the interrupt handler or that
someone else already disabled interrupts.
Looking more at it, there is actually no reason for these locks
anyway. Specifically the only reason you'd ever call
rpmh_rsc_invalidate() is if you cared that the sleep/wake TCSes were
empty. That means that they need to continue to be empty even after
rpmh_rsc_invalidate() returns. The only way that can happen is if the
caller already has done something to keep all other RPMH users out.
It should be noted that even though the caller is only worried about
making sleep/wake TCSes empty, they also need to worry about stopping
active-only transfers if they need to handle the case where
active-only transfers might borrow the wake TCS.
At the moment rpmh_rsc_invalidate() is only called in PM code from the
last CPU. If that later changes the caller will still need to solve
the above problems themselves, so these locks will never be useful.
Continuing to audit tcs_invalidate(), I found a bug. The function
didn't properly check for a borrowed TCS if we hadn't recently written
anything into the TCS. Specifically, if we've never written to the
WAKE_TCS (or we've flushed it recently) then tcs->slots is empty.
We'll early-out and we'll never call tcs_is_free().
I thought about fixing this bug by either deleting the early check for
bitmap_empty() or possibly only doing it if we knew we weren't on a
TCS that could be borrowed. However, I think it's better to just
delete the checks.
As argued above it's up to the caller to make sure that all other
users of RPMH are quiet before tcs_invalidate() is called. Since
callers need to handle the zero-active-TCS case anyway that means they
need to make sure that the active-only transfers are quiet before
calling too. The one way tcs_invalidate() gets called today is
through rpmh_rsc_cpu_pm_callback() which calls
rpmh_rsc_ctrlr_is_busy() to handle this. When we have another path to
get to tcs_invalidate() it will also need to come up with something
similar and it won't need this extra check either. If we later find
some code path that actually needs this check back in (and somehow
manages to be race free) we can always add it back in.

I've been pouring through the rpmh-rsc code and trying to understand
it. Document everything to the best of my ability. All documentation
here is strictly from code analysis--no actual knowledge of the
hardware was used. If something is wrong in here I either
misunderstood the code, had a typo, or the code has a bug in it
leading to my incorrect understanding.
In a few places here I have documented things that don't make tons of
sense. A future patch will try to address this. While this means I'm
adding comments / todos and then later fixing them in the series, it
seemed more urgent to get things documented first so that people could
understand the later patches.
Any comments I adjusted I also tried to make match kernel-doc better.
Specifically:
- kernel-doc says do not leave a blank line between the function
description and the arguments
- kernel-doc examples always have things starting w/ a capital and
ending with a period.
This should be a no-op. It's just comment changes.

The "cmd_cache" in RPMH wasn't terribly sensible. Specifically:
- The current code doesn't really detect "conflicts" properly any case
where the sequence being checked has more than one entry. One
simple way to see this in the current code is that if cmd[0].addr
isn't found then cmd[1].addr is never checked.
- The code attempted to use the "cmd_cache" to update an existing
message in a sleep/wake TCS with new data. The goal appeared to be
to update part of a TCS while leaving the rest of the TCS alone. We
never actually do this. We always fully invalidate and re-write
everything.
- If/when we try to optimize things to not fully invalidate / re-write
every time we update the TCSes we'll need to think it through very
carefully. Specifically requirement of find_match() that the new
sequence of addrs must match exactly the old sequence of addrs seems
inflexible. It's also not documented in rpmh_write() and
rpmh_write_batch(). In any case, if we do decide to require updates
to keep the exact same sequence and length then presumably the API
and data structures should be updated to understand groups more
properly. The current algorithm doesn't really keep track of the
length of the old sequence and there are several boundary-condition
bugs because of that. Said another way: if we decide to do
something like this in the future we should start from scratch and
thus find_match() isn't useful to keep around.
This patch isn't quite a no-op. Specifically:
- It should be a slight performance boost of not searching through so
many arrays.
- The old code would have done something useful in one case: it would
allow someone calling rpmh_write() to override the data that came
from rpmh_write_batch(). I don't believe that actually happens in
reality.

I was trying to write documentation for the functions in rpmh-rsc and
I got to tcs_ctrl_write(). The documentation for the function would
have been: "This is the core of rpmh_rsc_write_ctrl_data(); all the
caller does is error-check and then call this".
Having the error checks in a separate function doesn't help for
anything since:
- There are no other callers that need to bypass the error checks.
- It's less documenting. When I read tcs_ctrl_write() I kept
wondering if I need to handle cases other than ACTIVE_ONLY or cases
with more commands than could fit in a TCS. This is obvious when
the error checks and code are together.
- The function just isn't that long, so there's no problem
understanding the combined function.
Things were even more confusing because the two functions names didn't
make obvious (at least to me) their relationship.
Simplify by folding one function into the other.

The thermal trip points have unit name but no reg property, so we can
remove them. It also fixes the following warnings from 'make dtbs_check'
after adding the thermal yaml bindings.

As the domain-idle-state DT binding got converted to the json-schema, a few
minor changes were introduced. For example, the states needs to be
specified within a separate node, named domain-idle-states. Let's conform
to the updated binding.
This also silence the below errors for msm8916 from of 'make dtbs_check':
idle-states: cluster-retention:compatible:0: 'arm,idle-state' was expected
idle-states: cluster-gdhs:compatible:0: 'arm,idle-state' was expected
